ABSTRACT:
An electrophotographic copying machine device provided with a pair of lens arrays installed in parallel to enable variable- or actual-size copying and a means for selectively directing the light-path, allowing each lens array to select its light-path before projecting the original image onto a recording medium such as a photoreceptive drum, in which the copying device incorporates the following: equalizing the distance between original-scanning starting points for actual- and variable-size copying to the distance between light-exposure positions on the recording medium by applying variable-size lens array; equalizing the distance between light-exposure positions on the recording medium, corresponding to the original-scanning starting point, and the image transfer starting position, by which image on the recording medium is transferred to the transference material using the variable-size lens array, to the distance for transferring the transference material from its standby position to its transference position; and means for controlling engagement of the transference material held in a standby condition in response to the original-scanning operation activated with the variable-size lens array.
